These are small sacs in the ovaries, each containing an immature egg. At the start of each cycle, several follicles enlarge and one is selected to mature and release a mature egg: this is ovulation, which occurs in the middle of the cycle.

Every woman establishes her stock of follicles even before her birth, and this reserve diminishes throughout life until it is completely depleted: this is menopause. The follicles produce sex hormones. During the first half of the cycle, the follicle predominantly produces oestrogens, while the corpus luteum, in the second half of the cycle, produces progesterone.
